Oxalis corniculata L. is a medicinally important plant. Its medicinal usage is reported in different traditional systems of medicine such as Ayurveda , Unani & Sidha. It possesses important activities like antioxidant, anticancer, antimicrobial, antifungal, antihelmic, anti inflammatory, Kumar, et . al.14. In Chhattisgarh, O. corniculata L. popularly known as Tinpania bhaaji is being consumed as a leafy vegetable crop by the local masses. A periodic survey was made to collect the infected leaves of O. corniculata L. for pathological investigations. Cladosporium herbarum was isolated as a fungal pathogen from the leaves with large dark brown necrotic spots.. The pure culture was maintained on PDA slants for further studies. The presence of antifungal compounds, in higher plants, has long been recognized as an important factor in disease resistance. Four Angiospermic plant extracts viz: Cassia fistula (Cf) , Annona squamosa (As), Bauhinia variegata (Bv), and Aegle marmelos (Am), were tested in vitro against Cladosporium herbarum on the solid and broth media both. A. marmelos extract was found to be most effective in inhibiting the mycelial growth of C. herbarum whereas C. fistula extract exhibited minimum inhibitory effect.
